Abstract
The Zr70Ni16Cu6Al8 bulk metallic glass (BMG) was tested in tension mode using high-speed imaging in order to monitor the viscous flow inside a sliding shear band. Assuming the shear band thickness to be 15 nm, we estimated the shear viscosity to be ∼3.8 × 103 Pa s. The apparent temperature in the shear band was estimated to reach approximately 852 K on the basis of the relationship between the viscosity and the strain rate in the supercooled liquid region and was found to be considerably lower than the melting temperature (1293 K).
